Protective sports eyeglasses with buffer and shock-absorbing function

ABSTRACT

Protective sports eyeglasses with buffer an shock-absorbing function includes a cushion having a a hollow sealed endless shape. The cushion has a routine of a 3D tubular space instead of 2D (two dimensions) surface. The cushion is attached on an annular edge of a lens contacting the face of a wearer so as to suit to the curvature of a face, and has an inner pressure preset in advance so that the cushion may contact closely and comfortably the face of a wearer with buffer and shock-absorbing effect.

BACKGROUND OF THE INVENTION

[0001] Common conventional protective eyeglasses such as those used inswimming, diving, cycling, etc. generally have a cushion made of anelastic material such as a sponge or foam rubber to produce soft andcomfortable feeling in wearing it on a face.

[0002] However, when conventional protective eyeglasses receives strikeor shock, a wearer may suffer pain, harm or wound because of poorelasticity the cushions have, limited by its thickness and itselasticity coefficent.

SUMMARY OF THE INVENTION

[0003] In view of the disadvantages aforesaid of the conventionalprotective eyeglasses, this invention has been devised to offerprotective sports eyeglassed with buffer and shock-absorbing function,which has a cushion of hollow 3D space attached with a frame or a lensso as to produce soft and comfortable feeling in wearing it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] A first preferred embodiment of protective sports eyeglasses withbuffer and shock-absorbing function in the present invention, as shownin FIGS. 1-6, includes a lens 1 and a frame 2 independent from eachother and able to be firmly combined together. Further, a cushion 3 isprovided with the lens 1 on the side contacting with the face of awearer, formed integral with the lens at its peripheral edge, and havinga hollow interior. The cushion 3 is shaped as an annular hollow 3D ring,sealed and endless, so its route is not a surface. Further, the cushion3 is filled with a preset pressure, permitting it contact the face of awearer steadily and comfortably because of 3D curvature of the cushion3, having buffer and shock-absorbing effect. The cushion 3 is made ofmaterials having high density and low percolation, selected frompolyimide, polyethylene, polypropelene, acetic salt of ethylene,polyester, polyamide, polyurethane, chlorinated polyethylene, or butylrubber. Or materials having good elasticity, flexibility,anti-low-temperature, and easy processibleness can be used as well.

[0022] A second preferred embodiment of the protective sports eyeglasseswith buffer and shock-absorbing function in the present invention isshown in FIGS. 7-11, includes a lens 1 and a frame 2 formed integralwith the lens 1, and a cushion 3 made independent to be attached on theframe 2. The cushion 3 is an annular hollow 3D ring with a presetcurvature, not a flat two dimensions (2D). The hollow interior of thecushion 3 is filled with air pressure of a preset value. The frame 2 hasan annular groove 21 of a preset size for the cushion 3 to fit thereinwith close fitness and stability.

[0023] Another preferred embodiment of that shown in FIG. 7 is shown inFIGS. 12 and 13, includes a lens 1, a frame 2 having a flat surfacewithout an annular groove 21. The annular flat surface of the frame 2should be wide enough for attaching the cushion 3 thereon.

[0024] The cross-section of an inner or the outer shape at any point ofthe hollow 3D cushion 3 is all the same or not the same, of anygeometric shape. As the cushion 3 is made to have a hollow 3D shapeclosely contacting the face of a user, and a preset pressure in thehollow interior to minimize sport harm or wound with its buffer andshock-absorbing function in practical use, thus protecting the face fromhurt.

[0025] The inner buffer pressure filled in the cushion 3 may bepreferably in the scope of 0-40 psi, and then different buffer pressurecan be selected for different objects and different conditions, able tobe chosen by consumers. So at least one hollow passageway 30 may beadded to the cushion 3, communicating the cushion 3 with outer air, asshown in FIGS. 14-16, for connecting an air valve 301, a valve, a pump,or the like so as to fill the hollow interior of the cushion 3 with agas, a semi-fluid, a fluid, a liquid or low-percolating large particlegas such as SF6, C2F6, etc.

[0026] An inner pressure of the cushion 3 not communicating with outerair is produced with a special method, such as a process with a hollowmold placed in an air pressure container, forming a sealed cushion 3with the same inner pressure as that in the air pressure container,which is preset in advance.

[0027] While the preferred embodiments of the invention have beendescribed above, it will be recognized and understood that variousmodifications may be made therein and the appended claims are intendedto cover all such modifications which may fall within the spirit andscope of the invention.
